Abstract: A method and system for modifying virtual reality (VR) boundaries based on usage includes defining, using a virtual reality system including a computer communicating with head set, a safe area defining a geographic location for a user. The safe area is monitored for when the user strays into a second area beyond the safe area. The second area is defined in relation to the safe area that the user strayed into beyond the safe area. The user interaction in the second area beyond the safe area for safety is assessed, and a determination is made when the second area is safe based on a criteria. In response to the determining that the second area is safe, not initiating an alert to the user of being outside the safe area.

Abstract: Twirling confetti includes a plurality of devices, each said device comprising a thin flat member having a first side edge, a second side edge, a longitudinal center line extending between the edges, a first end and a second end. The member is configured so that the cross-sectional area of the member decreases from the second end towards the first end. An elongated rib extends between the ends to one side of the center line. A weight is connected to the flat member adjacent to the first end.

Abstract: A display control circuit controls the outputs of the three video DACs of an RGB monitor on a window-to-window basis to enable the display of motion video and text on the same screen with different brightness and/or tint. A digital overdrive signal, synchronized to the video DAC digital inputs, is used to enable added DAC elements for the pixels in the video windows only. Stored digital instructions determine how many and which added DAC elements are enabled by the overdrive bit(s). By storing different instructions for each of the three video DACs, the circuit may also provide window-dependent tint control. By increasing the number of bits of digital data synchronized to the digital DAC inputs, the stored instructions may be reduced or eliminated. In this case, each of several windows may be set to differing brightness and tint levels.

Abstract: A method and apparatus for dynamically regrouping display memory chips to efficiently implement 8-bit, 16-bit, and 24-bit per pixel display solutions is provided. The invention permits the implementation of 24-bit per pixel solutions in which 24-bit pixels do not straddle addressable regions, but without requiring the use of a unused byte of display memory per 24-bit pixel.
